Asked in Astronomy, Geometry
How many miles is an orbit of 220 miles high from earth?
Do you mean the length of such an orbit ? Well . . . -- The radius of the Earth is about 3,960 miles. -- 220 miles further out means that the radius of the orbit is 4,180 miles. -- The circumference of a circle is (2 pi) x (the radius). -- So the length of the orbit is (8,360 pi) = 26,264 miles. (rounded) ...
Asked in Science, Planetary Science, Planet Neptune
What is smaller an astronomical unit or the average size of Neptune's orbit?
Neptune's orbit has a mean radius of 30 AUs. The Earth's orbit has a mean radius of 1 AU, which is how an AU is defined, so 1 AU is much smaller than Neptune's orbit. ...
Asked in Astronomy, Planetary Science, The Moon
How far does Earth have to travel to go around the sun?
Since the Earth's orbit has a radius of about 150 million km., just multiply this by 2 x pi. The Earth's orbit is more or less a circle. Since the Earth's orbit has a radius of about 150 million km., just multiply this by 2 x pi. The Earth's orbit is more or less a circle. Since the Earth's orbit has a radius of about 150 million km., just multiply this by 2 x pi. The Earth's orbit is more or less...
Asked in Planetary Science, Dwarf Planet Pluto, Stars
What is the pattern in the time it takes the planets to orbit the sun?
Planets orbit the sun in proportion to the radius of their orbit. The Radius Cubed is proportional to the Time Squared. R3 = kT2 Therefore, R3/T2 = k (k will always be the same number) ...
The radius of the moon's orbit is how many times larger than the radius of Earth?
it is actually 265 to be exact (but most scientists round it to 321). "Radius" of moon's orbit, approximately 240,000 miles. Radius of Earth, approximately 4000 miles. Giving a ratio of approximately 60, not 265 or 321. ...
Asked in Planetary Science
How is the size of a planets orbit influenced by its distance from the sun?
The distance from the Sun IS the radius of the orbit - your question, as phrased is meaningless. ...
Why is Hubble space telescope orbiting earth faster than Space Station?
It doesn't orbit earth faster. The ISS is in a lower orbit with a period of 91 minutes compared to the Hubble's orbital period of 96-97 minutes. Orbital periods generally increase with orbit radius and speed in the orbit decreases with increasing orbit radius. ...
Asked in Skeletal System
What is the radius of the earth's orbit around the sun?
about 150 million km, but the orbit is elliptical instead of circular, this value is approximation ...
Asked in Astronomy
How far does the earth travel on one orbit of the sun?
The Earth is approximately 150 million km. from the Sun; that is the radius of the orbit, which can be approximated quite well as a circle. Therefore, multiply that radius by 2 x pi. ...
Asked in Astronomy, Artificial Satellites
What is the orbit radius of a near earth satellite?
The radius of earth is about 6400 km and for satellite to rotate around earth it's height must be greater than 36000 km for not to fall therefore orbit radius for such a satellite must be 6400+36000 = 42400 from the centre of earth ...
Asked in The Moon
Is the radius of the moon's orbit 0.6 or 6 or 60 times larger than the radius of earth?
My teacher told me it was 60 times.
Asked in Skeletal System
What happens to the energy of the electrons in the orbits as the radius of each orbit increases?
What happens to the energy of the electrons in the orbits of each orbit increases ...
Asked in Kinematics
How long would it take a satellite launched to a distance of 6700 km from the center of the earth to orbit the earth?
For stable orbit @ 6 700 000 metres Velocity = sq. root ( G * mass earth / orbit radius ) = 7713.576 metres / sec Time for (sidereal) orbit = (2 * pi * radius) / velocity = 5457.56 seconds. ...
Asked in The Moon
Can show us a diagram of the moon sun and earth orbit?
Draw a diagram using compasses. The Sun is at the centre and the Earth's orbit could have a radius of 4 inches. Put a spot somewhere on the orbit to represent the Earth. Then the Moon's orbit is a small circle round the Earth with a radius of 1/100 inch, about the size of a full stop. ...
Asked in Planet Mars
What is the speed of Mars relative to the sun?
Mars travels at somewhere around 24,000 m/s in its orbit around the sun. You can work this out by finding the distance of Mars to the Sun (the radius of orbit), finding the total distance of orbit (multiply your radius by 2*pi - assuming a circular orbit, which is ROUGHLY a good approximation), then divide by length of a Mars year. Enjoy. ...
